2004 Honda Civic Ex won't start

My son blew my head gasket. 120,000 miles. Replaced all gaskets, timming belt, new intake valves and adjusted the valves. Won't start?
Turns over and sounds like it wants to starts. Compression good, have spark and fuel. any thoughts?

If it sounds like it is trying to start you possibly have the firing order off. if that is not the case I would recheck the timing of belt to make sure you dont have one tooth off. stuff like that is so aggrivating, but if you have fuel and fire all you are missing is compression,if firing order isnt off, valves not being completely closed whent they need to be. due to improper timing.

easiest way is to get the dye and poor it into your engine. Then with the dye light you will be able to track the source. On those years the most likely spot was the intake manifold gasket and valve cover gasket. You also could have a blown head gasket that only blew on a oil intake side, doesnt mean that you would over heat

we need engine displace ment or exact honda type. ID
to answer fully.,
my guess, is the engine leaks oil and you have tried fix it
odd, you did the hard ones first. why not the valve cover
did you know there are 2 ways to find leaks.
1: clean it , all off, then run it and look. see live leak.
best is to do that with out driving as the wind blows it about.
find it , now you know what leaking.
2: use the UV dye kit.
quote wiki, but WHAT ENGINE ?????????????????
all base models were made with 1.6L engines. The EX-CX are all SOHC (Honda D engine). The CX, DX, and LX all have D16y7 non-VTEC engines; whereas the EX has a D16y8 VTEC, and the HX has D16y5 VTEC-E. The USDM Si and Canadian SiR came with a DOHC (B16A2 VTEC).

question, at the 60k mile service points. you check lash, settings.
with a new timing belt. and at such point, a new valve cover gasket gets fitted, did you? if yes, its not leaking if not>????
the front edge of the VC gasket, leaks down behind what i call
the VC leak hidder, tin pan. plate. behind the cam cog
is a plate, and the VC leaks down from there to the cam seal
then down front of engine, then past crank seal the, to cover.
seen this on all most all OHC engines...
cause, nobody does the 60k or does it and uses the old gaskets.
id look there first. but id dont have service history.
start high work down due to gravity.....
the FSM is here.
see that too. "free" toohttp://hondatech.info/downloads/Auto/Manuals/Civic/

After so many over heats.a car sometimes cant handle. after constant over heating your cars rubber gaskets could have gone bad and turned brittle letting in oil into spark plug well #1for your spark plug problem i would recommend changing your valve cover gaskets.and for the over heating and not turning on.i believe you blew a head gasket.

Did the timing belt break? Are you 100% that it is "in time" correctly? Does it spin over effortlessly? If so,do a compression check,and make sure you dont have any bent/broken valves,or blown head gasket.

thats correct the engine mount bracket needs to come off also if you need to remove rear timming belt cover to replace say the water pump or do some other repair, 3 torque head bolts are very tight and loctited in usually use correct torque socket and breaker bar to crack, its a bit of a tight squease also.

make sure they are tight
could be time for head gaskets
make sure the old gasket from the old filter came off the block sometimes they come off old filter and stick this causes a leak due to improper seal.
